Methods and systems provide creating and reporting of path annotations and renaming a state node using the path annotations for high level synthesis (HLS). In an embodiment, a method to annotate a state node includes identifying labels and pragmas specified in a high-level language input model for wait statements and function calls, and can also accommodate loops. In an embodiment, a method to display and/or report annotation information for a given state node includes displaying a state node name, an associated path annotation, and/or an associated hierarchical path. In an embodiment, a method to rename a state node based on a user-specified name includes using annotation information to locate a target state node and associating the target state node with the user-specified name or an automatically-created name based on the user-specified name. In an embodiment, a name specified for a state node can persist through successive runs of an HLS tool.

Annotations to identify objects in design generated by high level synthesis (HLS)

Systems and methods for storing waveform data and outputting data to a waveform viewer are disclosed. A waveform is segmented into a plurality of segments, and data describing each segment is stored at several levels of resolution. When a user wishes to view a portion of the waveform, the appropriate segments of the waveform are identified, and the appropriate levels of resolution are selected. The data describing the appropriate segments at the appropriate levels of resolution are output to a waveform viewer. An index may be provided to aid in selection of the appropriate data. Various methods for compression of the data are also supported.

A method and system for evaluating performance level models of electronic systems having both hardware and software components is provided. The system and method allow for the simplified implementation and testing of several different architectural designs for compliance with the desired operational requirement of a designed electronic system.
